webpack-loader with object rest spread plugin fails parsing

When trying to run sucrase with the webpack-loader and webpack-object-rest-spread-plugin I get the following error:

ERROR in ./src/Main.jsx Module parse failed: this.applyPluginsBailResult is not a function You may need an appropriate loader to handle this file type. TypeError: this.applyPluginsBailResult is not a function

Versions used:

webpack: 4.8.3
sucrase: 2.2.0
@sucrase/webpack-loader: 1.0.2,
@sucrase/webpack-object-rest-spread-plugin: 1.0.0

Thanks, glad to hear! I’ll actually reopen to track the task of updating the docs and maybe adding a runtime check.

@iki Take a look at https://github.com/webpack/webpack/issues/5548#issuecomment-395032615 , that may have some pointers. I think there are unfortunately some node_modules issues where it’s possible to be stuck on an old acorn even though webpack 4 should depend on a recent enough version that supports the syntax. The syntax works for me in webpack 4 with a fresh install, so maybe try reinstalling node_modules from scratch or regenerating your lockfile.
